...
- install the resistors and diodes
- install the ceramic capacitors (not the electrolyte caps yet)
- install the TO-220 regulators (IC4, IC5, IC7), the black isolated regulators do not match with the pcb holes, its not important. bend the pins as short as possible that they can be soldered from the rear-side of the pcb
- install IC3 - I prefer without a socket for better thermal regulation, but should be fine with a socket too.
- install the electrolyte caps
- install the LEDs - LED orientation - the square pad is ground (short leg) its the flat side of the LED designator
- install the fuse socket and MTA 156 2pole header
- install the DC-DC bricks (IC1, IC2)
- Double check the IC orientation and part values, Capacitor polarity
- wash the PCB carefully and let they dry over night
- optional - use a bench psu for testing with current limiter 12v /250mA 250- 500mA don't use a smaller current limit to avoid problems while start, the 250mA is a given value without any devices connected
- must do: all LEDs must be on, check against the given PCB voltages - all voltages must be correct
- Install the Heatsink by the self adhesive tape and push the heatsink against the DC-DC for 20-30seconds (new task since 24.Nov.2022)
...
first test on a bench PSU with current limit at 12v/200mA
Breakoutboard (BB)
Start with the SMT parts on the rear side and IC4.

12. the potentiometer must be installed with the front panel attached for best alignment - please note: one Potentiometer is not Center detent !! its marked on the pcb without an line in the circle.(volume pot)13. the potentiometer have to sit on the pcb - do not try to to install the potentiometers in a higher position (or you can run in problems with the knob heightthe circle.(volume pot)
14. there are 2 options how to do that.. but my shown option should be the best with separate nuts (no wobbling pots)
DO NOT try to install the nut on the frontpanel side !! install a nut as shown below .
15. OLED - install 2x M2 5mm Spacers on the OLED (you dont need 4 spacers) and respect the pinout as described in the Information List ID2 - its important to double check the pinout and measure the GND pad of the OLED against other GND pads on the HW.Board.
be careful with the OLED !!
LEDs:
here´s an example how to install the LEDs easily:
Put the HW board on the Mainboard:
install the spacers (12mm spacer between HB and MB) put the MB on the HB - then solder the headers on the pcbs
mount the bracket on the BB pcbs with 2 screws.
Cable/wiring:
We use MTA156 headers which can be used with cables of 1.5mm2 maximum.
the current is 1300mA at 12V under load, cable length is 0.5m max.
A = ( I x 0,0175 x L x 2 ) / (fk x U)
result is 0.75mm2 for 1m is safe !
(0.5mm2 is fine too since I used in my calculation 1meter and 2Amps)
testing
Test the PSU without BB - on a bench psu with current limiter 250mA only the PSU.
with mainboard connected 1000mA (without Voicecard)
with one card try 1000mA- with all cards up to 2.000mA
The OLED and LEDs will only work after you have installed the Firmware !! (some leds are on without the firmware)
Firmware Installation
The latest Firmware is on a separate page : ISE-NIN Manuals and Firmware

Firmware Installation
The latest Firmware and install guide is on a separate page : ISE-NIN Manuals and FirmwareInstructions for Flashing
• Connect STM LINK to the Motherboard with the ribbon cable from the programmer and connect the STlink programmer with your Mac or PC
• Turn ISENIN on
• Open STM Cube Programmer or ST LINK utility (cube programmer is the latest software, but STlink utility is fine too and often better)
• Select ST-Link, select connect (which reads the ISE-NIN uC memory)
• Select erasing and programming button (in STlink utility its "program & verify)
• Browse select ISENIN 1.0b-1.hex file from your pc/Mac. - Start programming ***
• Repeat the procedure described above and select ISENIN 1.0b-2.hex Start programming as before (program and verify)***you don't need to restart the ISE-NIN after first programming step, in case the ST-LINK tool hangs, just reconnect the USB cable.
• Disconnect and restart ISE-NIN – its important to remove the Programmer from the ribbon cable - or the device will not start !!

Calibration
Instructions for Calibrating

Here is a step by step guide to calibrate the filter resonance: (ONLY AFTER that you need to calibrate filters in further step)It´s recommend turning the resonance trimmer TR1 fully clockwise on each voicecard to make this procedure as easy as possible!  The best way is to use 8 resistors on the mainboard for making a measurement. 1. Warm up your unit about 30-40 mins 2. turn on ISE-NIN, Go to menu (press shift (grey cap button) + Back (middle button under the display), then calibration, choose resonanceCROSSMOD then press SHIFT and press the encoder, this will add the hidden RESONANCE and CROSSMOD TRIM function (its hidden since prebuilt units do not need this) (The display should read: "card 1" and you should hear a test tone through the outputs (for the next voice card you can press the "next (Back)" button to cycle through the voice cards) 3. Connect a Scope probe on the Mainboard, to the resistor of the card which you calibrate , set your oscilloscope to "timebase 0.5ms/cm" and "1V/cm" (on DMM: 0.5V -1V is fine too, depends on your scope screen resolution - some new scopes are HD resolution in 720p or more and the ADC are very accurat) 4. You should see the filter signal on your scope. If you have turned the trimmer fully clockwise the signal should be- and sound distorted. now turn the "resonance" trimmer TR1 on the Voicecard anti- clockwise until you get a clean signal as in the picture below (The difference of maximum and minimum amplitude in one cycle has to be 4-times.) make sure to have enough gain otherwise the Filter calibration step will fail as described in next section. Comment from Black Corp: "We especially made all settings in resonanse calibration how they should be (square, cutoff, 12db etc)."
Congratulations, you have successfilly calibrated the filter resonance for all of the voices! Resonance calibration Method according to the Roland Jupiter-8 service manual (not recommended yet → use above method!!!):Go into MENU, CALIBRATION, RESONANCE. Follow these steps from the Jupiter 8 manual, turning Trim1 for each voice (or see below):
Workaround or turn Trim TR1 until the self oscillation is off on each voice. you can switch between the cards using the switch button on the mother board. |
